GAS-REG U LATOR.

SPECIFICATION forming part of Letters Patent No. 644,625, dated March 6, 1900.

Application filed May 4, 1898. Serial No. 679,694. (No model.)

To (ZZZ whom it may concern:

Be it known that I, NORMAN MCBETH, a citizen of the Dominion of Canada, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Gas-Saving Checks; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention has reference to gas-saving checks, and is intended to operate in two directions-viz., to prevent back pressure upon the meter and excessive forward pressure upon the burners.

To these ends the invention consists in the construction and combination of parts, substantially as described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of a gas meter of any common kind and having sections of the supply and service pipes, respectively, connected therewith in their usual relation. Fig. 2 is an enlarged central sectional elevation of the end of the service-pipe so specially designated for distinction from the supply-pipe to the meter and having my improved check in vertical section therein. Fig. 3 is a perspective elevation of the checking device itself as it is made for the trade.

A represents any ordinary meter, whether for common illuminating, natural, or other gas.

B is a section of the gas-supply pipe to the meter, and O is a section of the service or outgoing pipe which leads from the meter to the building.

D is my new gas-saving device or check, so called because it checks the pressure and flow of the gas both ways and thus works a material economy or saving in the volume of gas consumed and prevents unfavorable action on the meter by reason of back pressure from the service-pipes. The device itself is a simple and single article of manufacture and sale and is easily applied by the consumer in his own property and without in any manner tampering with or disturbing the mechanism or the function of the gas-meter, which almost universally belongs to the gas company.

Hence the device D is constructed and adapted to be inserted in the end of service-pipe O, substantially as seen in Fig. 2, which pipe is separably and temporarily united with the meter by the coupling E. This common and universal form of coupling renders detach ment of the pipe 0 easy, when it can be moved aside and the checking device placed within by any unskilled hand.

Now, referring to the device itself, 2 repre sents the shell or body thereof, which is cylindrical in general outline and has a flange 3 about its bottom, adapted to engage or rest against the end of pipe 0 and serve as a stop or limit when the device is placed in position, as well as practically sealing the passage. In cross-section the bodyD is relatively smaller than the interior of the pipe 0, and this especially enables springs 4 to be made 'available for holding the device up in place. These springs in this instance are in one piece with the interior cross-bar 5 and bear frictionally but firmly against pipe 0 toward their free ends. These or any equivalent springs or like fastening medium may be used.

Within the body or shell 2 is a conoidal bottom insertion 6, resting at its top against the shoulder 7, formed annularly about and in the lower portion of the shell 2 and with its small end down and forming a seat for valve 8. This valve is seated from above in the flaring bottom 6 and has a stem 9 engaged in the cross-piece 5, which serves as a guide therefor as the valve rises from and returns to its seat. Finally, a conical or conoidal dome 1O surmounts the body 2 and has a comparatively-small outlet at its top in the form it is ofiered in the market-say relatively to the body of the device about as shown. The lines of taper of the dome or top 10 are straight and project from the body 2 to the opening 61 in point, and are purposely so made to enable the device to be readily adapted to the needs of the place Where it may be used. Thus, supposing that as sold to the trade the hole 01 is large enough to ac= commodate a service of the smallest kindsay a residence where half a dozen or thereabout of burners are used. For such purposes the device is ready for use as it is pur chased. But suppose the service calls for twenty or thirty burners. In that case the passage (Z would be too small to supply gas to all the burners at a suflicient pressure for the best results. Then the advantage of my novel construction of top becomes available, and the party who sets the check and has knowledge of his business simply runs a file across the passage (1 until he has made it large enough to afford a healthy supply of gas to the increased number of burnres found at that place, whether they be twenty or fifty or a hundred. In other words, starting with the minimum of capacity in passage d the passage is enlarged according to the greater needs of any case, whatever they may be. Hence the tapered construction of the top 10, which makes it easy to enlarge passage 61 with afile, as described.

In operation valve 8 rises under pressure from below to accommodate the flow through passage (1, while it effectually shuts off back pressure from the service pipes upon the meter.

\Vhat I claim is 1. A gas-check having a cylindrical body with an outwardly-extending flange about its lower edge and a tapered top terminating in a central passage, and a valve inside the check arranged to seat downward, thus cutting off back pressure on the meter, substantially as described.

2. The gas-check having a flange about its bottom to bear against the end of a pipe, and springs on its outside to frictionally engage in the pipe, substantially as described.

3. The pipe, the gas-check therein having a cylindrical body, and a spring extending through said body and bent at its sides to bear against the pipe and hold the body in position, substantially as described.

4. The check having a conical top with a circular passage and a flange about its bottom and valve-seat, in combination with an inside valve seated from above, substantially as described.

5. The gas-checking device having a cylindrical body with a tapered top having an outlet at its center and said body provided with an opening in its bottom, in combination with a valve in said body arranged to close said opening from within the body and means to hold the device removably in the end of a service-pipe, substantially as described.

Witness my hand to the foregoing specification this 2Gth day of April, 1898.
